Jemima Khan has launched the #wakeupcall campaign for UNICEF, encouraging people to make a donation to help children affected by the Syria crisis.

The public are asked to post a photograph of themselves first thing in the morning with the hashtag #WakeUpCall. Khan, who came up with the idea following a recent trip to Jordan, commented 'Please help make my campaign to raise awareness for Syria's 6.5 million children affected by the conflict a success'. There has already been support on social media from the likes of Naomi Campbell, Keeley Hawes, Stephen Fry, Nigella Lawson and Hugh Grant.
